298 NATURAL HISTORY OF PLANTS. 
Seeds reniform or suborbicular, much compressed, exarillate— 
Herbs, undershrubs, or more rarely shrubs, glabrous or shaggy; 
leaves pari- or imparipinnate ; leaflets small, usually falcate exstipel- 
late: stipules persistent, membranous or scarious; flowers’ in short, 
often 1-lateral, racemes; bracts and bractlets scarious or striated, 
persistent ; bractlets appressed to flowers (Zropical Asia, South-eastern 
Africa’). 
133. Discolobium Brnrs.’—Calyx gamosepalous ; lobes 5, nearly 
_ equal or 2 superior connate. Petals shortly unguiculate; standard 
suborbicular; wings obovate, about equal to standard ; keel shorter 
than wings, nearly straight, obtuse. Stamens 10, 1-adelphous, finally 
evenly 2-adelphous ; the sheath becoming longitudinally cleft on both 
sides ; “ vexillary and lowest stamens almost free from base ;” anthers 
uniform. Germen shortly stipitate pauciovulate; style curved 
glabrous; stigma minute oblique terminal. Legume short, at 
superior suture nearly straight, at inferior expanded into 3 horizontal 
segments or disks; middle segment largest reniform reticulated 
fertile 1-seeded indehiscent; lowest and highest sterile, much 
smaller. Seed lunulate-reniform exarillate—Undershrubs ; leaves 
imparipinnate ; leaflets oo or more rarely 1, 3, exstipellate ; stipules 
small; flowers‘ in axillary racemes; peduncle elongated rigid ; 
pedicels solitary ; bracts and bractlets small persistent (Brazil’). 
134. Ormocarpum Pat. Bravv.'—Calyx gamosepalous ; lobes 5, 
unequal; 2 superior broader, close or connate to a variable extent ; 
lowest often longer than others. Standard suborbicular unguicu- 
late; wings obliquely obovate; keel about equal to wings, broad 
curved, obtuse or rather acute at apex. Stamens 10, connate into a 
sheath often finally longitudinally cleft above and below; anthers 
uniform. Germen sessile; ovules « ; style slender, much inflexed ; 
apex not thickened or minutely capitate, stigmatiferous. -Legume
